Enter the voltage and resistance into the calculator to determine the current in amperes. This calculator can also evaluate any of the variables given the others are known.
Ohms To Amps Formula
The following formula is used to calculate the current in amperes (Amps) from resistance in ohms (Ω) and voltage in volts (V).
I = V / R
Variables:
- I is the current in amperes (Amps)
- V is the voltage across the circuit in volts (V)
- R is the resistance in ohms (Ω)
To calculate the current in amperes (Amps), divide the voltage across the circuit by the resistance. This is based on Ohm’s Law, which states that the current passing through a conductor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance between them.
What is Ohms To Amps?
Ohms to Amps is a conversion process used in electrical calculations to determine the current flow, measured in amperes (Amps), in a circuit when the resistance, measured in ohms (Ω), is known. This conversion is based on Ohm’s Law, which states that the current passing through a conductor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance between them. Therefore, to convert ohms to amps, the voltage across the circuit is also needed.
How to Calculate Ohms To Amps?
The following steps outline how to calculate the Ohms To Amps using the formula: I = V / R.
- First, determine the voltage across the circuit (V).
- Next, determine the resistance (R) in ohms.
- Next, gather the formula from above = I = V / R.
- Finally, calculate the current in amperes (Amps).
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
voltage across the circuit (V) = 12
